That's usable size. The tank itsrlf is about 13 gallons.
Obviously propane use depends on how warm you kerp your interior and how exposed you are to direct sunlight (warmth) during the day. Also depends on if your refrigerator is on ac power or propane. Presuming you are not plugged to shore power and kerp the temp st 68 at night, I would expect a full tank to last at least 2 weeks. I have gone longer than that with my 2015 model 2551,but I run the generator during the day and use a ceramic heater and/or the heat strip to keep things warm during the day. Obviously, the other reason I run the generator is to recharge the house batteries.
Thanks for the info on the tank size!
I am surprised that you believe the tank would last 2 weeks. That would be great! I could probably live with a one week answer just not a few days as that would get very annoying.

I can only talk about my experience. I have spent lots of nights on Walmart lots where temps from mid-teens on up and coach batteries are still fine in the morning. Again, depends on how warm you want it. I have been in near zero temps, but on shore power, and used... Maybe 1/10th of a tank of propane a dsy. Now, admitedly, during daytime, I was driving and just using engine heater. If you're talking mostly 40's and 50's I believe 2 weeks is reasonable, especially if you drive during the day.
No matter what, you'll need to run generator or drive to recharge house batteries during the day.
At 10 to 12 hours a day to run generator for air conditioning you can easily use 1/2 a gasoline tank (about 25 gals) every 3 or 4 days.
